Abstract

The invention provides a plugging loop test bench of an electromobile charger interface. The plugging loop test bench is simple in structure and convenient to use, and is used for the plugging loop test of the electromobile charger interface. The plugging loop test bench of the electromobile charger interface comprises a frame, and an air cylinder and a position sensor used for detecting the position of a piston of the air cylinder are mounted on the frame. The air cylinder is communicated with an air source through an electromagnetic directional valve, and the electromagnetic directional valve is electrically connected with the position sensor. The frame is provided with a fixing part used for fixing the charger interface to be detected on the movement route of the piston of the air cylinder. According to the plugging loop test bench of the electromobile charger interface, the position sensor and the electromagnetic directional valve are used for controlling stretching of the piston of the air cylinder, so that the plugging loop test is achieved, the overall structure is simple, adjusting is convenient, manufacturing cost is low, and good practicability is achieved.

Description

technical field [0001] The invention belongs to the technical field of vehicle product testing, and in particular relates to a plug-in and pull-out cycle test bench for a charger interface of an electric vehicle. Background technique [0002] The electric vehicle charger interface must have reliable and durable characteristics, so design verification must be carried out before it is put into use. The plug-in and unplug cycle test of the electric vehicle charger interface refers to the normal use of the electric vehicle charger interface. It should be able to withstand normal The mechanical, electrical and thermal stresses that occur during use without excessive wear or other harmful effects reflect the ability of an electric vehicle to charge properly and its useful life. If the test is performed manually, it not only increases the labor cost, but also makes it difficult to guarantee the test quality. Therefore, a test bench that can test automatically is urgently needed. ...
